   Which pair of solutions forms a buffer solution when equal volumes of each are mixed?
   
   a. 0.20 M HCl and .20 M NaOH
   b. 0.40 M HC2H3O2 and 0.20 M NaOH
   c. 0.20 M HCl and 0.20 M NH3
   d. 0.40 M HCl and 0.20 M NH3
   
   Thanks

   Is this Chem II? because I don't know "buffer solution". This problem is in ACS.

   Yes this is Chem II. There are 2 version of the ACS exam. One is for first semester (chem I) and the gen chem exam is for chem I and II. Was your course I or II? We did a big long chapter on buffers in chem II.

   Yes, its inorganic II. If you bought the ACS review book, it'll contain both inorganic I & II. But you won't see questions like this on the inorganic I exam.
